Two recent flashlight developments, intended to conceal the rays against visibility from above so the lamps may be used safely during a blackout, consist of a flashlight with built-in hood and a shield which may be trimmed to fit any flashlight. With the hooded flashlight, a strong beam may be aimed straight ahead, but the hood prevents side glow. The shield, attached to any ordinary flashlight, provides a window that opens or closes for a clear or subdued light. It is inserted inside the lens-holding ring, and if it does not fit exactly it may be trimmed easily with a pair of scissors to the right size.
